TO ALL WHOM IT MAY OONOERN:

Be it known that we, WILIJAM P. LUrToN and C. M. TALBOT, ci' Oadia, in the county of Harrison, and State of Ohio, have invented a new nndimprored RegisteringYnrd-Stick; and we do hereby declare the following to be-a full, clear, and exact description of thesaine, reterencebeinghad to the accompanying drawings forming part of this specification, and in which- `Figure l represents aback view of our invention, showing the internal mechanism as though the slide s were transparent.

Figure 2 is a cross-seetion through line o; a: of iig. 3, and

Figure 3 is a longitudinal section through liney y ot lig. 3.

In this invention the operator registers the number ot' yards measured by pressing a knob projecting from the side of the stick under his finger as he measures each yard. The number of thcltally is indicated by figures appearing through a small aperture in the back of the yard-sticlc.

Similar letters of reference indicate corresponding parts in the several iigures.

In the drawings, A indicates the body of the yard-stick, which is graduated and marked as usual. In the back of'the stick is a slide, s, running the whole length ot' the stick, which can be readily removed in order to expose the internal mechanism of the instrument. On the rear side et the stick, (the left side in lig. 2,) under the slide s, is a chamber, C, from which a long narrow slot, c', is cut through to a-eountcrsink, e, extending along the centre of the front side. In the bottom of the chamber C a bed is eut out, along which slides a graduated plate, D, numbered from 0 up te any required extent. The side of thc plate opposite to the figures is cnt into a ratchet, or the plate is fixed to a ratchet-rod, r, the teeth of which projeettowards the front side ofthe instrument. When the slide s is on, the graduated face of thc plate D comes against its under side, and through an aperturc,E, in the slide, some one number on the graduated scale can be s een at all times. V is a small spring, which presses the graduated plate against the slide S, to prevent its slipping or moving when not acted upon by the rod r.' A pin, e, projects through the slot e', from the 'ratchet-rod or plate D, its head boing protected by the counter-sink c. F. is `a slide, from which a knob, 7c, projects through a small slot in the edge of the instrument, by which the slide F can be morcd back and forth. A spring, g, keeps the slide F thrown forward toward the graduated plate at all times, except when itis held back by force applied at the i knob 7c. From the slide a rod, 2', terminating in hook, extends along under the plate D, the hook coming in contact with the ratchet-teeth of the plate, and when the knob k is pressed down in the' direction of thc spring g, drawing the graduated plate down with it just one degree, the movement of the knob k being too limited to4 allow it to draw the sliding-plate more than one degree at a time. A little piroted lever, Z, to which is attached a pin, o, projecting through the slot c in the same manner as the piu c, serves to throw the hooked rod z' out of connection with the ratchet 7' whenever it is necessary to slide tric graduated plate back to its first position. '.lhc rod z', being itself a spring-rod, at all other times remains in contact with the ratchet.

This completes the construction of my device. It now remains to describe its operation and uses.

In measuring cloth, the operator takes the instrument in his right hand, resting his fore-linger over the knob Measuring one yard, he presses the knob slightly with his linger, and it registers l; then another, and another pressure of the knob,and 2 is registered, and so to any required number. Its operation is thus simple, easy, and accurate, preventing all possibility of mistake in counting. In invoicing goods, itgives the number 'of 'ards in the whole ieee without countinff. .lf the measurinc is interrupted and resumed afterwards noy e. C a 7 grcater danger of mistake exists, as the record of the quantity tallied at first remains on the instrument. At

all times it is just as easy to measure with this improved yard-stick as with the old one, and the operator can count the number of yards as 11e goes along, if he chooses. When hc is done he can verify his count by examining the register on the instrument, and if hc has made any error it'will be revealed at a glance. When the measure is finished, ard the operator desires to return the graduated plate D to its original position with 0, Shown at the aperture E, so as to be ready for measuring another piece, he presses slightly upon the pin o, which disconnects the hooked rod t' from the ratchctr, and leaves the plate D free to slide in either direction. By means or" the pin c he then runs the slide back to its original position. The whole is only the work of an instant.

Having thus described our invention, what We claim as new, and desire to secure by Letters Patent, is The sliding graduated plztt'e D, in combination with a. yard-stick, substantially :is and for the purpose described.

2. The combination ofthe sliding graduated plato D with the knob it, rod rate-liet r, and spring g, sub# stantially as and for the purpose specified.

3. The combination of lever Z, ratchet r, rod z', pin e, and pin o, for the purpose of disconnecting the actuating-rod and ratchet, and replacing the plate D, substantially as described.
